LED lamp bead price differences: how to choose high-quality products

With the continuous development of the LED market, the price difference of LED lamp beads has become more and more significant, and the quality is uneven. In this market, the appearance of each product does not look very different, but the price war has led to uneven quality levels.How long is the life of LED lamp beads?

In order to help consumers make informed choices when purchasing LED lamp beads, some key factors in the manufacturing process will be revealed below for your reference.

The criticality of the die bonding process

Solid crystal is a part of the LED lamp bead production process, involving the fixation of the chip. The material of the bracket, such as aluminum, brass and copper, has a significant impact on the thermal conductivity of the lamp beads. Aluminum brackets have poor thermal conductivity, followed by brass, while copper has the best thermal conductivity. Products that choose copper stents are more expensive, and some manufacturers may reduce costs by using defective or adulterated products, posing quality risks to users.

The authenticity of LED chips

LED chip is the core component of LED lamp beads, and its quality directly affects the performance of the product. There are some counterfeit chips on the market. Their appearance is the same as regular products, but their internal structure and performance are very different. When purchasing LED lamp beads, be sure to choose products from regular manufacturers to ensure the quality and performance of the chips. Here are 4 common sense about LED display chips.

The impact of welding wire materials on quality

Bonding wires connect the chip and the bracket, and the gold wires selected include alloy wires and pure gold wires. The cost of alloy wire is lower, but it is easy to cause the lamp beads to break. In comparison, pure gold wire is more expensive, but has better ductility and can better cope with the frequent lighting and switching off of lamp beads.

Phosphor selection in dot powder process

The powder dotting process involves applying phosphor powder on the chip to adjust the light color of the lamp beads. High-quality phosphors are more expensive, and low-end products may use lower-cost phosphors, causing the problem of lamp color temperature drift. When purchasing LED lamp beads, pay attention to whether the product uses high-quality phosphors to ensure the stability of the light color.

Glue selection in the glue filling process

During the glue filling process, there are two main glue options: jelly glue and spacer glue. Jelly glue is more expensive, has a crystal clear appearance, and is suitable for high-end products. There are differences in the quality of spacer glue. 80% of packaging factories may use lower-priced spacer glue, which affects the quality of the product.

The criticality of spectroscopic technology

The spectroscopic process adjusts the color temperature of the lamp beads according to customer needs. Low-end products may not perform spectrometry, resulting in lower shipment rates. When purchasing, it is recommended to choose products that have been subjected to spectroscopic processing to ensure that the color temperature of the lamp beads meets expectations.

Conclusion

To sum up, the price difference of LED lamp beads stems from the selection and technical level of multiple links in the production process. When purchasing LED lamp beads, consumers need to carefully identify product quality, choose appropriate products, and avoid performance and lifespan problems caused by low prices. Only by selecting high-quality LED lamp beads can we ensure the stability of lighting effects and service life.
